BOBBIN-CLEANING DEVICE.

Specification of Letters Patent.

Patented Apr. 7, 1914.

Application filed November 6, 1913. Serial No. 799,432.

To all whom it may concern:

Be it known that I, JosnPI-r F. VAILLAN- COURT, a citizen of the UnitedStates, and residing at Fall River, in the county of Bristol and Stateof Massachusetts, have mvented certain new and useful Improvements inBobbin-Cleaning Devices, of which the following is a specification, suchas will enable those skilled in the art to which it appertains to makeand use the same.

This invention relates to what are known as bobbin cleansers, wherebywhat are known as thread stubs may be quickly and easily removed from ashuttle bobbin without ury thereto, and so that the bobbin may berewound with thread.

In the operation of the shuttles of looms, the thread, when partiallyexhausted from the bobbin, frequently becomes stuck thereon or locked sothat it will not unwind. The amount of thread on the bobbin at thistime, is called a stub and this stub must be removed before the bobbincan be rewound with thread. Hereto-fore, it has been customary to cutthrough the stub longitudinally of the bobbin with a sharp knife so asto remove the stub from the bobbin, but this frequently results ininjuring the bobbin. It has also been customary to grasp the stub andbobbin in the hand and then strike the smaller end of the bobbin on theloom frame, or any other object, a number of times, which operationwould result in sliding the stub off of the bobbin, but this operationis difficult and.

frequently ineffectual, and the object of this invention is to provide adevice of the class specified which is simple in construction andoperation, and by means of which a stub may be quickly and easilyremoved from a bobbin, without injury to the latter.

The invention is fully disclosed in the following specification of whichthe accompanying drawing forms a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe Views, and in which Figure 1 is a side view of a shuttle bobbinprovided with a stub of thread Fig. 2 a longitudinal section of myimproved device for removing the stub from a bobbin Fig. 3 is a viewsimilar to Fig. 1 and showing the method of using my improved bobbincleaner, and Fig. 4 a cross section on the line l-l of Fig. 2.

In the drawing forming part of this specification, I have shown at a anordinary shuttle bobbin such as is used in all looms, and the bobbin ais provided at its larger end with a head a and the bobbin shown isprovided adjacent to the head a thereof with a stub Z) of thread.

In the use of bobbin shuttles of the class specified, after the threadwound thereon has been partially used, the thread frequently catches orbecomes fastened in some way so that it will not unwind, and this formswhat is called a stub, as shown at Z), and it-is necessary to removethis stub from the bobbin before the bobbin can be rewound. The devicewhich I employ for this purpose'is shown at 0 in Figs. 2, 3, and 4:, andis tubular in form in cross section and larger at one end than at theother, the smaller end being provided, in the construction shown, withan annular head 0 The bobbin cleaner 0 from the head 0 to about themiddle thereof is preferably of the same size, but from about the middlethereof to the opposite end, the said bobbin cleaner is enlarged, thisenlargement being a gradual taper, in the form of construction shown,from the said end toward the middle of the device. The bobbin cleaner 0is divided centrally and longitudinally into two similar parts 0 and theopposite sides of the enlarged end thereof are provided in the planethat separates the parts thereof, with longitudinal V-shaped recesses0*, and one part is preferably provided with longitudinal flanges o inwhich the side edges of the other part fit.

An elastic band or retainer d, of any kind or construction, is passedaround the smaller end of the device adjacent to the head 0 for thepurpose of holding the separate parts together and in operativeposition.

From the foregoing description, it will be seen that my improved bobbincleaner consists of two jaw members, yieldingly connected and into orbetween which a bobbin with a stub of thread is adapted to be inserted,and the use of this device in removing the stub Z) from the bobbin isindicated in Fig. 3, and in this operation, the cleaner is slipped onover the smaller end of the bobbin and onto the stub Z), and the largerend of the said cleaner is grasped in the hand and pressure is appliedthereto so as to cause the larger end of the cleaner to grasp and holdthe stub, while the smaller end thereof, or the side portions thereofare separated and free from the body of the bobbin, and the smaller endof the bobbin is then struck a number of times on the frame of the loom,or any other object, and in this operation, the stub is slid off of thebobbin which may be rewound in the usual manner.

The inner walls of the bobbin cleaner are preferably provided withannular ribs, teeth or projections c, and in the construction shown, thesaid inner walls are tapered from one annular rib, tooth or projection,to another, but this exact construction is immaterial, and the saidinner walls of the cleaner or the separate parts thereof may be providedwith'any kind or class of inwardly directed teeth or projections inorder to fa-' cilitate the grasping and holding of the stub b, as shownin Fig. 3, and while I have shown and described the preferred form of myimproved bobbin cleaner, my invention is not limited to the details ofcon: 'struction herein shown and described, and various changes thereinand modifications thereof may be made, within the scope of the appendedclaims, without departing from the spirit of my invention orsacrificing. its advantages.

Having fully described my invention What Iclaim as new and desire tosecure by Letters Patent is V 1. A hand operated bobbin cleanercomprising two oblong jaw members between which a bobbin with a stub ofthread is adapted to be inserted, said jaw members being concavo-convexin cross section and adapted to be grasped by, held in, and operated byone hand, and to be compressed on said stub of thread. 7

2. A hand operated bobbin cleaner comprising two similar jaw membersbetween which a bobbin with a stub of thread is adapted to be inserted,said jaw members being provided in their inner faces with longitudinalgrooves, and being also tensionally connected at one end.

3. A hand operated bobbin cleaner of the class described, said cleanerbeing tubular in form in cross section and being composed of two similaraw members between which a bobbin with a stub of thread is adapted to beinserted, said jawmembers being tensionally connected at one end.

4a A hand operated bobbin cleaner of the class described, said cleanerbeing tubular in form in cross section and being composed of two similarjaw members between which a bobbin with a stub of thread is adapted tobe inserted, said jaw members being tensionally connected at one end,and being separated at the other end by V-shaped recesses. 5. A deviceof the class described which is tubular in form in cross section and ofpredetermined length and larger at one end than at the other, saiddevice being divided centrally and longitudinally into separate similarparts, and the separate parts atthe larger end being separated bylongitudinal V-shaped recesses.

6. A device of the class described which is tubular in form in crosssection and of predetermined length and larger at one end than at theother, said device being divided centrally and longitudinally intoseparate similar parts, and the separate parts at the larger end beingseparated by longitudinal V-shaped recesses, and said parts beingprovided at the smaller end with a yielding con nection.

7. A device of the class described which is tubular in form in crosssection and of predetermined length and larger at one end than at theother, said device being divided centrally and longitudinally intoseparate similar parts, and the separate parts at the larger end beingseparated by longitudinal V-shaped recesses, and said parts beingprovided at the smaller end with a yielding connection, and the innerwalls of said parts being provided with inwardly directed projections.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this third day of November1913.
